We consider an ARMA-GARCH model extended to include dummies and other exogenous variables that affect market prices, such as RES and Hydro electricity production, as well as load volumes and Brent crude oil prices. In order to analyse the impact of the regulatory reforms on price and volatility dynamics, we include regime dummy variables, reflecting the timeline of these reforms. Based on the results, we discuss the impact of the examined reforms and their significance.

The two sets of scores for physical and transition risks aggregate exposures to various risk factors, taking into account the adaptation and mitigation capacity of each country. The scores confirm that climate risk is a relevant challenge for all countries. However, low-income economies are more vulnerable to physical risk - in particular to acute events, rising sea levels and excessive heat - and in parallel have lower ability to mitigate the challenges posed by the energy transition. High-income economies generally face higher risks from the transition to a low-carbon future. Countries more dependent on fossil fuel revenues are also among the most exposed to transition risk. This paper provides insights into the model as it is currently being developed. Understanding the relative cli...

Tariff deficits are shortfalls of revenues in the electricity system, which arise when the tariffs for the regulated components of the retail electricity price are set below the corresponding costs borne by the energy companies. The objective of this paper is to define and identify the different cases of electricity tariff deficits in Member States. The analysis starts with a description of the functioning of the electricity market in Europe, including price formation and different forms of government intervention, such as support to renewable energy and retail price regulation. Then the paper determines the existence of tariff deficits in the various Member States on the basis of common criteria and describes their common features, as well as particular characteristics of tariff deficits in the countries concerned. An econometric analysis is carried out to identify th...

Nevertheless, many energy efficiency investment opportunities do not materialise. The existing literature attributes this situation to financial and non-financial factors. Research suggests that many firms focus only on direct energy savings and neglect non-energy benefits that include increased labour productivity. Up to date, due to lack of high-quality data, few studies attempted to quantify the effects of the energy efficiency investments on firm-level outcomes other than the reductions in energy consumption. This paper overcomes this barrier by using novel data from a firm-level survey conducted by the European Investment Bank that covers more than 15,000 firms in 27 European Union member states and the UK during 2018-2019. It studies the relationship between the energy efficiency investment and the labour productivity of the European firms, utilising instrumental variables methodology to...

It benefits from the data collected within the European Investment Bank Surveys in 2017 and 2018, involving information about energy audits and energy-efficiency investments of some 12,500 signatures from EU28 Member States per year. Our findings suggest that energy audit is a useful tool in overcoming the information barriers and facilitating investments in energy-efficiency measures. In fact, their information is more crucial for small firms and for investments in support processes such as lighting, wall insulation etc. than in production processes such as replacement of machinery and equipment. However, we found that the beneficial impact of energy audits cease to exist when firms are finance constrained. Finally, our results indicate that information campaigns are one of the most efficient available instruments among other instruments (regulatory, financial and voluntary agreements) fo...

The empirical analysis uses the 384kbps connections since for the period examined, over 85% of the total ADSL customers in Greece are connected at this bandwidth. The empirical analysis is based on an ad-hoc specification of the demand equation, with no reference to the utility maximization problem of the representative consumer. The results of the analysis show that both demands are inelastic. In addition, cross-price elasticity for ADSL is negative, indicating that ISDN is a complement to ADSL, whereas the demand for ISDN is almost neutral to ADSL.

The substantial investment in low carbon technologies that will be needed to achieve these ambitions will have to be supported by an economic and institutional framework capable of facilitating the transition.
